Create a data group

Before you can access data from an OPC Server, you
need to define the data group to which it belongs. A data group is
a way to organize data retrieved from the OPC Server into logical
selections of related data.

Note: OPC Clients usually allow properties
to be set on a per group basis, such as the rate at which the data
is collected. therefore consider arranging and naming your groups
according to these requirements.

As this procedure is OPC Client-specific, refer to
the documentation accompanying your OPC Client.
